Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] An embodiment of the on-site safety protection device of a kind of foundation pit construction of the present invention, as Figure 1 to Figure 10As shown, it includes a plurality of fixed protection mechanisms; each fixed protection mechanism also includes a fixed mechanism and a protection mechanism. The fixing mechanism includes an upper fixing plate 13 , a lower fixing plate 16 , a fixed insertion rod 15 and a plurality of hinged rods 14 . The lowe...

Abstract

The invention relates to the field of support transposition, in particular to an on-site safety protection device for foundation pit construction. A lower fixing plate is horizontally arranged on the ground above a foundation pit, and an upper fixing plate is horizontally arranged above the lower fixing plate. The upper end of a hinge rod is hinged to the upper fixing plate, and the lower end of the hinge rod is hinged to the lower fixing plate. A protection mechanism comprises an upper protection plate, a lower protection plate and a protection barb. The upper end of the upper protection plate is fixedly connected with the upper fixing plate and used for making contact with a foundation pit wall. The upper end of the lower protection plate is inserted into an inserting groove in a sliding mode. Tension springs are arranged in the inserting grooves and located between the upper protection plate and the lower protection plate, the upper ends of the tension springs are fixedly connected to the upper protection plate, and the lower ends of the tension springs are fixedly connected to the lower protection plate, so that when the lower protection plate slides downwards under the action of gravity, the tension springs are driven to stretch and store force, and then the upper fixing plate is driven to move downwards; and the pressure of the upper protection plate and the lower protection plate on the foundation pit wall is increased through the hinge rods, so that the protection effect is enhanced.

Description

technical field [0001] The invention relates to the field of support devices, in particular to an on-site safety protection device for foundation pit construction. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size. Before excavation, the excavation plan should be determined according to the geological and hydrological data, combined with the conditions of the nearby buildings, and the waterproof and drainage work should be done well. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the slope size is determined according to the relevant construction engineering regulations. If the excavation is deep and there are buildings nearby, the foundation pit wall support method and the shotcrete retaining wall method can be used to prevent the foundation pit wall from collapsing. [0003] In the process of strengthening the founda...
